NiFe_2O_4磁性纳米材料的溶剂热法一步合成
|
摘要
以Fe(NO_3)_3·9H_2O和Ni(NO_3)_2·6H_2O为原料,在未添加任何碱性沉淀剂和高温晶化处理的条件下,通过对实验条件(包括溶剂、溶剂热温度和时间)的优化,利用溶剂热法一步制备了具有良好结晶性和超顺磁性的NiFe_2O_4磁性纳米材料。结果表明:用H_2O和EtOH-H_2O做溶剂都不利于NiFe_2O_4的生成;用EtOH做溶剂,为了获得纯度较高的NiFe_2O_4磁性纳米材料,要保证适当的溶剂热温度和时间;所得材料的磁性能与材料中磁性组分NiFe_2O_4的含量和其结晶程度有关。该制备方法最突出的优点是简单、快速、成本低、从源头消除了污染,且所得的材料磁性能优良。
Through optimizing the experimental conditions(including solvent, solvothermal reaction temperature and time), NiFe_2O_4 magnetic nanomaterial with good crystallization and super paramagnetic performance, was prepared by one-step solvothermal method using Fe(NO_3)_3·9H_2O and Ni(NO_3)_2·6H2O as raw materials and Et OH as solvent without adding any alkaline precipitation agent or high-temperature crystallization process. The results show that the solvents, H_2O and(H_2O+EtOH), are disadvantageous to the target magnetic species NiFe_2O_4.Under the condition of Et OH as solvent, the proper solvothermal temperature and reaction time must be guaranteed in order to obtain NiFe_2O_4 magnetic nanomaterial with high purity. The magnetic properties of prepared materials are related to the content of NiFe_2O_4 and its crystallization degree. The prominent advantages of this preparation method are of simpleness, speediness, low cost, free pollution from the source and friendly-environment. And the prepared materials have excellent magnetic performance.
